Looks Natural, Sounds Great - Traditionally, rock speakers have looked like ornaments and not like rocks. Each RS PRO series loudspeaker style has unique textures and colors that are fashioned after natural rocks. Shaped grilles match the features on the front of the rock, making them blend into the cabinet. All of this extra attention to detail leads to a GeoRealistic style that enables the these loudspeakers to blend in with other landscaping and disappear. All that will be noticed is the great sound not the loudspeaker.

Weather Proof Construction - The custom cabinet is made from multi-layer fiberglass; it utilizes double seals on the tweeter, woofer and enclosure cover, and is designed so that the woofer drains water away from it. The grilles are painted rust-resistant aluminum and the acoustic drivers are made from weather resistant materials. The RS PRO series loudspeakers have passed some of the most stringent environmental tests devised. It survived over 5 years' worth of temperature cycling and still having seals that pass a 24-hour submersion test. They have passed the test requirements for Salt Fog, Operating Temperature, Storage Temperature, UV Exposure and Humidity per the stringent military test standard 883. Whether you are concerned about salt-air, rain, freezing rain, snow, extreme temperatures, high humidity, direct sunlight or combinations of these conditions, the RS PRO series has proven itself to withstand the harshest conditions Mother Nature can throw at it. Install with Confidence - The best-built loudspeakers deserve the best protection - the Niles Lifetime Limited Warranty.

Injection Molded TCC Woofer Coils - The unusually stiff and light injection molded TCC (talc, carbon, and ceramic filled) polypropylene cone, the butyl rubber surround, and the substantial magnet and motor structure are optimized for large excursions of the woofer. In this way, the woofer can create superior bass output.

Dual Voice Coil WoofersThe dual voice coil design of the SI models have the added advantage of being able to play in stereo when wired in Stereo Input mode.

Advanced Weather-Resistant Tweeters - In the past, many rock speakers have used a co-axial tweeter design that has disappointed listeners with a fatiguing and harsh treble sound caused by tweeter ringing. The advanced 1" Teteron tweeters found in our RS6, models utilize a tri-laminate design consisting of an inner textile layer which forms the dome, a high damping layer to kill unwanted resonances and an outside layer of urethane to add stiffness and prevent breakup modes. The result is a transparent clear, sweet, natural sounding tweeter, which still maintains its extended frequency response.

Tweeter Placement Improves Coverage and Dispersion - The tweeters are angled twenty degrees up from the woofer. The dual tweeters of the Si models are also angled twenty degrees from each other. This means thatthe tweeters are 'aimed' at the listener and not at the ground.

Dual Precision CrossoversA customized electronic dividing network inside the cabinet precisely distributes the music to the woofer and each tweeter, keeping the two channels completely isolated from each other. The three pole two-way design of the crossover provides excellent stereo imaging into each channel, low distortion and superior sonic performance.

ConeForward Design - Other rock speaker manufacturers mount their drivers from inside the cabinet. This moves the front of the driver inside the cabinet creating a tunnel for the driver to play through. This tunnel adversely affects the sound quality by making the loudspeaker sound "narrow" and "far away". Niles' engineers have used a proprietary ConeForward design technique that moves the woofer and tweeter as close to the grille as possible. Combining the ConeForward design technique with tight manufacturing controls leads to unparalleled sonic performance and imaging from an outdoor rock loudspeaker.

Rigid Acoustically Inert Cabinet Construction - Niles utilizes a unique multi-layer cabinet construction to achieve superior non-resonance of the loudspeaker cabinet. This ensures that all you hear is the music and not the cabinet ringing.

Low Diffraction Microperf Aluminum Grilles - The aluminum MicroPerf grilles on the RS PRO series loudspeakers have hundreds of precisely sized perforations, creating an acoustically transparent grille. The aluminum construction resists oxidation enabling years of trouble-free operation in the harshest conditions. We paint both sides of the grille for added protection.

Connection Cables with Water Resistant Wire Nuts - Connecting the loudspeaker's cable to the cable running from the house is always a point of concern for the installer. If this connection is not done right, the cable may corrode and the connection may fail. To make sure this connection is trouble-free, we provide three-foot connection cables rated for burial underground and specialized waterproof wire nuts. Our wire nuts are filled with a waterproof sealant. Just insert the wires and twist them together. Then bury the cable. The connection will be protected from the elements.

Security Bracket and Cable - Using the security bracket and cable supplied with the loudspeaker provides a simple but effective method to protect the loudspeaker from theft or unapproved movement. You can easily upgrade our standard security mounting method to provide even greater security, if you require it.

Selecting the number and location for your speakers - The RS PRO series loudspeakers loudspeaker can be installed directly on the ground, in a flowerbed, on a wood deck or on a concrete/stone patio. When choosing the location for the loudspeaker, take into consideration the slope of the land in the area the speakers are going to be placed. The flatter and more level the area, the better. The woofer should be straight up and down or tilted forward a bit to assist in drawing water away from it. Never choose a place where an automatic sprinkler will be aimed on or near the loudspeaker. While the loudspeaker is weatherproof, continuous streaming water will shorten the product's life. Please refer to the installation manual for more information regarding selecting the number and location for your speakers.

Incorporating a Volume ControlIt is possible to control the volume of the sound at the speaker location. Volume controls are connected in line with the speaker. It is usually desirable to control the volume of the speakers in different areas or zones of an outdoor speaker system. Niles recommends a standard weatherproof volume control. In addition to controlling the volume of the loudspeakers, these controls allow the addition of added speakers without adding more amplifier channels.
